说明：  简单的PID控制器建模，可通过simulink直接搭建模型实现(Simple PID controller model can be built directly through the simulink model implementation)

it contents some basic code to finding root of a equation

VDSL的上行链路仿真，满足以下指标： 1.下行（局端到用户端）速率：20Mbps，上行（用户端到局端）速率：5Mbps；传输距离为500m；在Eb/N0 = 15dB时实现误比特率Pe<=10-4 2.可用信道频谱：0.138MHz-12MHz 3.双绞线模型采用RLCG模型，传输介质为0.4mm PE cable (simulation of VDSL up link)

设计信号用快速傅里叶变换求信号频谱功率谱(Fft spectrum signal design requirements)

启动摄像头、并将摄像头拍摄下来的视频保存下来。matlab代码(Start the camera, and save the video)

基于matlab,利用AMDF方法检测语音的基音周期(Based on matlab, the use of methods AMDF Pitch Detection of Speech)

PWM 2 SIMULATION MODEL

用水平集做的 MRI大脑图像分割 内有用法说明 （带图形界面）-是学生做毕业设计的时候，应该可以参考下的(To do with the level set in the MRI brain image segmentation has usage instructions (with graphical interface)- is designed for students to do graduate, it should be able to refer to the)

本程序仿真了均匀线阵的泰勒方向图加权的函数。可以直接在Matlab中调用本函数。(taylor tapering of uniform linear array.)

说明：  摘要：用MATLAB对基带数据传输解调检测进行仿真，推导不同先验概率下，接收端最小错误的判决门限。仿真不同先验概率下的误码性能，二进制与多进制的误码性能比较，码间串扰对误码性能的影响，及频偏对串行通信误码率的影响。 关键词：MATLAB，基带传输，检测，判决门限 (Abstract: Using MATLAB for baseband demodulation simulation data derived under different prior probability, the receiver decision threshold minimum error. Simulation under different prior probability of error performance, binary and multi-bit error performance of binary comparison ISI on the BER performance, and the offset of the serial communication error rate. Keywords: MATLAB, baseband transmission, detection, decision threshold)
